Embodiment Construction

[0027] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] refer to figure 1 , briefly explaining a method for implementing hard handover between access networks in a connected state according to an embodiment of the present invention. Such as figure 1 As shown, the method roughly includes the following steps: S102. Before instructing the access terminal to establish a connection with the target-side access network, the source-side access network transmits the identification information of the access terminal to the target-side access network; And S104, the target-side access network demodulates the access terminal according to the identification information of the access terminal, so as to implement hard handover between the source-side access network and the target-side access network.

[0029] Wherein, the source-side access network adds the identification information of the...

Abstract

The invention discloses a method for realizing hard handoff between access networks in a connection state. The method comprises the following steps: S102, a source side access network transmits identification information of an access terminal to a target side access network before instructing the access terminal to establish connection with the target side access network; and S104, the target side access network demodulates the access terminal according to the identification information of the access terminal to realize the hard handoff between the source side access network and the target side access network. The method can help solve the problem that a channel unit of the target side access network can not demodulate the access terminal when the access terminal establishes the connection with the target side access network so as to smoothly realize the hard handoff between the networks.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for realizing hard switching between access networks in a connected state. Background technique [0002] In a Code Division Multiple Access (CDMA for short) system, there are three sequences, which are long codes, short codes, and Walsh codes. [0003] Among them, the long code is obtained by adding a pseudo-random code generated by a 42-bit shift register and a 42-bit long code mask (Long Code Mask, referred to as LCM) through AND gate modulo 2, and the long code of each channel The mask is different, the long code mask is also generated through a 42-bit shift register. The length of the long code mask is 2 42 -1. In a CDMA system, the long code is used to identify an Access Terminal (AT for short) on a reverse traffic channel. [0004] On the reverse traffic channel, the long code mask is divided into MI RTCMAC and MQ RTCMAC . According to the p...
